Rooftop Unit

A rooftop unit (RTU) is located on top of a building. The application will depend on a lot of variables such as location of the appliance, gas pressure used efficiency needed design national and local gas installation codes

A rooftop unit (RTU) is simple compact self-contained rooftop unit  located on the roofs of shops and small commercial buildings to provide air conditioning air to defined areas these are packaged air conditioning units are so popular because they are simple compact self-contained all in one HVAC units, There purpose is distribution of air to defined areas with in a building, rooftop units are connected to ductwork which provides a defined route for the condition air to travel alone

Furnace Installation/Repair/Maintenance

At mechanical Masters we do understand that your time is precious, and a furnace is something you never really never think about till it stops working with a little bit knowledge is much easier to troubleshoot minor problems.

Basics

Let’s learn how gas furnaces work first will cover the basics, Although there are some differences all gas furnaces work in the same basic way natural gas is burned up to warm up the heat exchanger.

The exhaust fumes gases, I released through the flue gas vent. The blower fan then pushes the air over the heat exchanger and circulates around your home. The furnace runs until the room  thermostat reaches the right temperature and shuts down the furnace. Newer furnaces use an inducer draft fan to move the flue gases, This forced draft also increases the efficiency, Condensing furnaces use a dual heat exchanger to condensed water vapour to extract more heat out of the flue gases.

Efficiency

Furnaces are rated by a AFUE or (annual fuel utilization efficiency) this number is a ratio of the fuel burn versus the fuel converted into heat.

Older furnaces will have an efficiency rating of 70 AFUE or less meaning that only 70% of the fuel is turned into usable heat. Mid efficiency furnaces are around 80 and high-efficiency condensing furnaces are generally 90 and above. Furnaces can be single stage or dual stage which means it’s either full heat or no heat, 2-stage furnace can run at full speed or a reduced speed when less heat is needed this allows for the furnace to run quieter and maintain a more consistent temperature.

Safety

Modern furnaces have a set of safety switches that shut down the furnace when the system is compromised, if a switch is tripped it will cause a furnace to lockout, the furnace will attempt ignition several times before going into a hard lockout for up to an hour every time a lock code happens the furnace will use flashing lights as code to identify the source of the shutdown these codes are unique to each model so check your furnace manual to see what each code means.
